There's no other reason but to offer as much flexibility as possible to our airlines. Many of us would have preferred harmonizing the regime across-the-board to have only one ratio,1:50, to simplify things, but airline companies, namely, preferred having more flexibility. As far as we're concerned, as long as the level of safety is the same under both regimes, we have no objection to maintaining a dual system.
The 1:40 regime we are proposing today is identical to the current one. The 1:50 regime has been supplemented by the mitigation measures we have already spoken to.
